A DeSoto ISD high school was vandalized twice and feces were found in parts of the school, police said.

At least one person broke into the school, vandalized it and stole from the girl's locker room and multipurpose room over the last two weekends, KDFW-TV (Channel 4) reported.

In the second incident, feces were found in the areas where athletes keep their belongings, police said.

Police have questioned a juvenile, but no arrests have been made.

"We do consider this an isolated incident, only involving one maybe two students that we're aware of ... the evidence has led us to these students and these students alone," police spokesman Sgt. Nick Bristow told the station. "We are disappointed that these offenses have occurred, and it is an isolated incident."

At a school board meeting Monday night, some parents blamed a lack of adequate security at the school.

"Our daughters would not have been traumatized, and we would not have been at the school until 11 o'clock last night cleaning up feces off their lockers and their clothing," parent Geraldine White told the station.
